I have two TextBoxes, two ListBoxes, a Cancel button and an OK button.
Simplifying the problem, I would like to link the color of the Borderbrush of the second ListBox to the IsEnabled property of the OK button.
An alternative would be link that color change to the ListBoxItem background instead of the Listbox border itself.
Is it possible (maybe through Triggers or something)? If so, could you show me the way?

Here's a small example that changes the border brush of a listview based on the IsEnabled property of a button
<StackPanel>
<ListBox Height="100">
<ListBox.Style>
<Style TargetType="ListBox">
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=okButton, Path=IsEnabled}" Value="false">
<Setter Property="BorderBrush" Value="Red"/>
</DataTrigger>
<DataTrigger Binding="{Binding ElementName=okButton, Path=IsEnabled}" Value="true">
<Setter Property="BorderBrush" Value="Blue"/>
</DataTrigger>
</Style.Triggers>
</Style>
</ListBox.Style>
</ListBox>
<Button IsEnabled="True" Name="okButton">true</Button>
</StackPanel>
But I would set the availability of the button on the command and not in the XAML, also I would bind the color of the ListView to the IsValid property in the ViewModel instead.

How can I make the ListView/Layout scroller to behave like modern layout like in android or windows 10. Currently the ListView scrollbar only applies to the ListView itself. I want the scroller to scroll the whole layout including the search bar in XAML.
I want also the ListView Items added to increment to the overall height of the ListView to achieve the effect.
Any available ways to do it with Native wpf xaml (No frameworks/dlls, just pure xaml/c#)

Put your ListView, search bar, and whatever else you want to scroll inside of a ScrollViewer.
Below Is my Code
I tried the method below, but for every button I get the same row number: 0, I think that is because the first button is default placed at 0th row.
Button btn = sender as Button;
if (btn != null) {
row = Grid.GetRow(btn); // And you have the row number...

Firstly, thank you for taking the time out to read this post. All contributions are very much appreciated.
I'm having difficulty understanding how I can bind a ComboBox ItemsSource within a DataTemplate to an ObservableCollection.
Here's my code thus far:
DataTemplate Template (notice the combo's at the bottom of the template):
<DataTemplate x:Key="ListBoxCustomTemplate">
<Grid Margin="4" HorizontalAlignment="Stretch" x:Name="lstBoxItemRoomGrid" >
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" FontWeight="Bold" Text="{Binding TemplateGroupName}" />
<Image x:Name="imgDeleteListBoxItem" Grid.Row="0" Grid.RowSpan="2" Grid.Column="1" Source="/Icons/Print-Groups-Config/delete-32.png" Height="25" Cursor="Hand"
ToolTip="Remove template" VerticalAlignment="Center"
HorizontalAlignment="Right" MouseLeftButtonUp="imgDeleteListBoxItem_MouseLeftButtonUp">
<Image.Style>
<Style>
<Setter Property="Image.Visibility" Value="Hidden" />
<Style.Triggers>
<DataTrigger Binding="{Binding IsMouseOver, ElementName=lstBoxItemRoomGrid}" Value="True">
<Setter Property="Image.Visibility" Value="Visible" />
</DataTrigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
<TextBlock Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2" Text="{Binding TemplateDescription}" TextWrapping="WrapWithOverflow" />
<!-- Header Template Selection -->
<Label Grid.Row="2" Grid.Column="0" Margin="0,3,0,0" HorizontalAlignment="Left" VerticalAlignment="Bottom" Content="Select Header:" FontWeight="DemiBold" Foreground="DarkGray" />
<telerik:RadComboBox x:Name="radComboHeaderTemplate" Grid.Row="3" Grid.Column="0" Width="120" Margin="0,0,0,0" HorizontalAlignment="Left" VerticalAlignment="Center"
ClearSelectionButtonVisibility="Visible" SelectedValue="{Binding TemplateHeaderID}" />
<!-- Footer Template Selection -->
<Label Grid.Row="2" Grid.Column="1" Margin="0,3,0,0" HorizontalAlignment="Left" VerticalAlignment="Bottom" Content="Select Footer:" FontWeight="DemiBold" Foreground="DarkGray" />
<telerik:RadComboBox x:Name="radComboFooterTemplate" Grid.Row="3" Grid.Column="1" Width="120" Margin="0,0,0,0" HorizontalAlignment="Left" VerticalAlignment="Center"
ClearSelectionButtonVisibility="Visible" SelectedValue="{Binding TemplateFooterID}" />
</Grid>
</DataTemplate>
When my Window loads, I download the collection data from my database and store into a local collection. Note that there are two Collections, one for each of the 2 ComboBoxes in my DataTemplate.
//Header Templates
private ObservableCollection<TemplateHeaderFooter> templatesHeader = new ObservableCollection<TemplateHeaderFooter>();
//Footer Templates
private ObservableCollection<TemplateHeaderFooter> templatesFooters = new ObservableCollection<TemplateHeaderFooter>();
//--- Constructors ---
public PrintTemplateGroupsConfigWindow()
{
InitializeComponent();
//Download Data From DB
this.templatesHeader = TemplateHeaderFootersDB.GetAllTemplatesOfType(1);
this.templatesFooters = TemplateHeaderFootersDB.GetAllTemplatesOfType(2);
}
How do I get the collection Data templatesFooters & templatesHeader into the the ItemsSources of their respective ComboBoxes?
The datatemplate is for a ListBox.
<telerik:RadListBox x:Name="lstBoxPrintGroupTemplates" Height="300" Width="280" ItemsSource="{Binding}" IsEnabled="False"
ItemTemplate="{StaticResource ListBoxCustomTemplate}" Style="{StaticResource DraggableListBox}" >
Many thanks. Any help is appreciated.
Define properties wrappers over the variables of your collections and then you can bind them to comboboxes as:
ItemsSource="{Binding TemplatesHeader, RelativeSource={RelativeSource AncestorType={x:Type Window}}}"
public ObservableCollection<TemplateHeaderFooter> TemplatesHeader
{
get{return templatesHeader;}
}
Similarly you can do for other property

..... More code.
The result looks like this:
Which looks nice. The trouble is even when I enter valid values for a TextBox a red border remains. Like you can see in the title and full name TextBoxes here. How do I remove this residue red border? Where is it coming from?
I've come across this before, when it happened to me I had to perform a data change during initialize and ContentRendered. Cause I had the items actually bound.
Another thing I saw awhile ago on Stack Overflow was an issue that happened here that also caused something similar.
<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate>
<ControlTemplate.Resources>
<BooleanToVisibilityConverter x:Key="converter" />
</ControlTemplate.Resources>
<DockPanel LastChildFill="True">
<Border
BorderThickness="1"
BorderBrush="Red"
Visibility="{Binding ElementName=placeholder, Mode=OneWay, Path=AdornedElement.IsVisible, Converter={StaticResource converter}}">
<AdornedElementPlaceholder x:Name="placeholder" />
</Border>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
That was my encounter, if that doesn't help I'll attempt to recreate the issue and fix as well. See if I can help you out a little better then describing how I fixed it. But hopefully one of those two suggestions helps you out.
Just let me know, hope it helps.
I have a WPF listbox and have updated the list item data template to have essentially a 3 column layout.
I would like:
|status color|name| buttons|
These are probably CSS terms but I want to float the status color and name to the left, which I've done, then I would like the buttons to be floated to the right, and always stay to the right even as the window gets wider.
I feel like I'm so close, the list item widths grow when the window gets wider, all I feel I have to do is tell the buttons to float right but can't figure out how. I've tried stack panels, a grid with a auto|*|auto column layout (With a stretch on the last column) and I've tried a dockpanel.

And an image of what I'm trying to achieve:
The problem is at the first level below DataTemplate, here:
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
By its nature a StackPanel will align items to the left, so it's not a layout that's well suited to what you want to do. Instead try using a Grid with two columns, giving the left column Width=* and the right Width=Auto.
<ListBox HorizontalContentAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" Orientation="Vertical">
...
</StackPanel>
<DockPanel Grid.Column="1" VerticalAlignment="Center">
...
</DockPanel>
</Grid>
<DataTemplate>
</ListBox.ItemTemplate>
<ListBox>
In your ItemContainerStyle, set the HorizontalAlignment to Stretch. I believe it is Left by default, which may be causing the Grid or StackPanel or whatever container you use to collapse.
